I currently have an AT9 dish and an H20 receiver. I live in the Greensboro, NC market so I get my local HD's through the dish. I'm trying to see if a multiswitch would help me. I would like to add a DVR and 3 more rooms to my account. I was told that a DVR with dual tuners requires 2 feeds from the dish, which would only leave me with 2 free feeds for the other 3 rooms. Can a multiswitch help me? If so how do they work? Thanks, Todd
